To 217mm ilmc cciicc/ Be it known that it, Enron (banner, of German nationality, residing" at lilannhcim, (,l'ermany, have invented a new and use'iul improvement in Machines for ll orking U p Ceramic Masses into Tiles, Disks, and Similar bodies tor which I filed, an application in Germany October ll, 11920, No 52382 VI/80A, not yet granted, and oi which the following is a specification.

This invention relates to improvements in machines tor working up ceramic masses into tiles, disks and similar bodies and the object thcreot to enable ceramic masses of a fatty tcxtiu'e and especially ceramic masses containing :1 high percentage oi nonplastic ingredients or cl :1 very lean tex ture to be built up into large cylinders blocks and such like bodies, wherein are contained a number oi? the articles to be made, and these bodies to be trued to tinished size and cut into disks, tiles and such like articles in one setting up.

In the accompanying drawings l have illustrated novel machines tor carrying out my improved process. In the drawing Figure l. is a lateral view t the whole machine with supporting column on the left and cutting oft device and tile rest on the right.

Figure 2 shows the cutting off device and tile-rest by itself seen from the column and table.

Figure 3 is a view of the tile rest.

Figure 4 is a section on line 4i-4 of Figure 1 through the column and bolder.

Figures 5 and 6 show details of: the tilerest.

Similar letters refer to similar parts throughout the several views.

The machine consists of the bed a. on which the column 0 bolted to foundation plate 6 slides by means of the chain wheels 03 and d rack and pinion; the table a vertically adjusted by rack, pinion and hand wheel, carries the cylindrical ceramic body 7 shown as an example, which is to be cutup into circular disks or slabs.

The cylinder is first of all trued up on the periphery to finished size by means of the revolvingknife Z carried on the telescopic spindle g which rotates through the bevelled wheels 71 71 and h and step cone pulley 2' of which the lower portion can be raised and lowered by lever 7c in the usual wayv lijllGl'QLlpOll the arm carrying spindle which swivels on column 0, swung out of the way through an angle 01. about 90 and the cutting up of the cylinder into disks begins.

Column 0, carrying the cylindrical body f slides on bed (i towards the two belt driven pulleys in carrying a narrow band saw n and, by passing the cylinder along between these two pulleys m the disks are completely sawn off by the band saw 71, the vertical position oi the cylinder having obviously been fixed to the desired height by means of the above mentioned hand wheel, rack and pinion.

in view of the comparatively small cohesion oi the lean ceramic objects, of which the bodies consist, the disks must be supported during the cutting off period, as otherwise the overhanging portion of the disk which is being sawn oil", will break as soon as the saw n has penetrated to a certain depth into the cylinder. The tilerest or catching device provided for this purpose ronsists of U shaped tension frame 0 with the open end towards column 0 over which a number of steel bands are tightly drawn in the same plane as the saw. I

These steel bands enter whilst cuttingbfi into the cutting or interspace between disk, which is being severed and the remainder of the block, fill it practically up and being of the same thickness as the saw blade, they support the disk. which is being cut oil, during the cutting off period, providing a rest tor it. Figure 5 shows two of these steel bands from above and Figure 6 is a section through the tension frame with tension device for the steel bands.

The gaps between the two steel bands will take up the shavings generated when cutting.

lVith masses containing non-plastic material ot fine grain with cylinders of a small diameter, a perforated sheet across the tension frame or a similar rest of corresponding thickness can be used instead of the steel bands.

The V shaped holder 9 fixed to column 0 adjustable horizontally by means of two teethed shafts and slotted, as at in the height of the saw blade, details of which are given in Figure 4, showing section 4-4 is pushed up during cutting ofi' period against the cylinders prevents the tilting" 0t same the breaking on of the outside edge of the disk and the cylinder, as the blade breaks throngln and seri s at the same time to push. the disk which hashcen out oft with case on the steel-band rest.

The slot provided in the holder allows the saw to advance tar enough.

This holder can also have the shape of a quadrant or any other shape corresponding to that oi. the block or cylinder,

After a disk has been cut off, the column a and with it the cylinder f return to the original position where it necessary the upper portion oi? the peripher -J is trncd up by the aifore described revolving knife Z.

The table 6 is thereupon raised by means oi: the mole pinion and handwhcel or any other mechanical device to the height corresponding to the thickness of the next disk to be cut oil and the-prone s o't cutting; off is repeatedv the disk previously sawn oil', which is now ready for burning having been removed from the support.

here disks provided with centre holes are wanted, for instance is the case oi grinding wheels, a corresponding drill inserted into the hollow sleeve at the bot tom end of the spindle f/ and the wheel is bored simultaneously and the periphery ot the cylinder turned by means of the revolving knite Z.

This knife should not he too long" and only a portion of the cylinder should be turned up at one time and after cutting off that portion, the cylinder should return to the position centrally beneath spindle g and a further portion should be trued up.

The machine will serve also for cutting oft square, rectangular or any other irregular shapes, whereby the sides are worked up on the machine over templets. the holder 9 altered accordingly and the revolving knife Z not used.

Where large disks or slabs are to be made it will be advantageous to provide a revolving table instead ol a stationary one and to rotate the blocks or cylinders truing the periphery with a stationary tool.

The principle of the invention can also be carried out in such a way that the cylinders are laid horizontally on a support of the cor responding shape and slotted according to thickness of the disk wanted or by beddingthe cylinders or blocks on some plastic supe port, which can easily be cut and cutting these blocks by means of a vertical. band saw of well-known construction into disks slabs or tiles.

The process may be also utilized for cutting; up masses containing small perceno'f non-plastic matcriah especially where these have been made by the castinp; or slush process.

I claim 1. In a machine for making disleshaped objects and the like from ceramic masses a vertically adjustable support for a mass block; means tor trninp; the mass; means for successively cutting disks from the mass and means to; *ceiving and supporting the cut disks the said adjustable support and the said disk cutting means being arranged for relative movement toward and from each other.

in a machine tor making disk shaped and similar objects from. cerrnnic masses, a

mass supportinc table; swing arm carried by the machine a rotating rising and. talling spindle on said swing arm, a rotating knife carried thereby andarrai' 'ed to true the mass and a saw for successi ely cutting disks from the mass said table being mounted for movement toward and i in said saw.

3. in a machine for making disk-shaped objects and the like from ceramic masses. a vertically adjustable support for mass block; means tor truinp; tl e mass; means to]? successively cutting disks from the mass, and means tor receiving and supporting the cut disks the said adjustable support and the said disk cutting means being arranged for relative movement toward and from each other, and the said mass truing means being arranged for movement to and from the mass block.

4:. In a machine for making disk shaped and similar objects trom ceramic masses, a mas block supporting table; a cutting member in the machine a shaped. tension :trame provided in conjunction with the cutting member; and steel bands drawn overthe said ii rame and separated from each other by small interspaces said bands being of the same thickness as the cutting member and adapted to support the objects as they are cut otl'.
